@longshin777 To clarify, Gonsuke has never been referred to with a pronoun in the manga, at least as far as chapter 3. I believe Gonsuke is most likely female, but chose to use the masculine "he" pronoun as Gonsuke is a very masculine sounding name. Seeing as how the protagonist named Gonsuke, this leads me to believe that Tetsu thinks Gonsuke is male, as well.
Random disinterested internal monologue while passively failing to get beat up by Thugs A, B, and C is an interesting place to finally put an infodump on what the setting is XD
I was wondering why he seemed so calm, but then they mentioned the ogre/orc blood and it suddenly made sense. Alo explains why he can survive the hits from Gonsuke in a way other than "comedy armor". I wonder if he also got strength from them.
